Abstract

PROBLEM TO BE SOLVED: To immediately stop supply of a carbonated beverage such as barreled draft beer by a foam shutoff device when much foam is supplied from the inside of a barrel. SOLUTION: Only a liquid component of a carbonated beverage separated by a gas-liquid separation board, which enters the foam cutting device 2 is discharged downward from a discharging opening 71 formed between a lower face of the gas-liquid separation board and an inner cylinder 56 while being guided by a downwardly inclined taper 68. If a float valve 63 rises due to the liquid component of beer or the like inside, the valve 63 is not affected by the discharged fluid. Foam is separated by the gas-liquid separation board 58 and discharged upward from a hole on a top plate 66, wherein a flange notch faces immediately above it, so that the float valve may not be affected by the foam. If the foam increases in amount to cause the float valve 63 to lower, a flow discharged from the opening 71 comes against a stage 78 of the float valve, causing the float valve 63 to rapidly lower.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foam circuit breaker for a foamed beverage supply device for blocking foams of a foamed beverage supplied from a container storing a sparkling beverage such as draft beer.

[0002]

2. Description of the Related Art When selling draft beer stored in a keg, carbon dioxide gas is filled in the keg and the draft beer is extruded.
This is cooled down through a cooler and distributed to mugs and the like. That is, as shown in FIG. 15, a dispenser head 142 is attached to an outlet 141 of a draft beer barrel 140 as a sparkling beverage container, and a gas pipe 145 of a carbon dioxide gas cylinder 144 as a gas supply source is connected to the dispenser head 142.
The extraction pipe 146 is connected, and the high-pressure carbon dioxide gas of the carbon dioxide gas cylinder 144 is supplied into the draft beer barrel 140 through the pressure reducing valve 147, and the draft pushes the draft beer in the draft beer barrel 140 to the extraction pipe 146 due to the pressure. The draft beer is cooled through the cooler 148 and extracted into the mug 150.

In the apparatus for supplying carbon dioxide into the draft beer barrel 140 as in the above apparatus, when the draft is exhausted in the barrel, the lower end of the supply pipe 143 in which the carbon dioxide is suspended to the bottom of the barrel. When the curan C is opened, high-pressure gas is blown out, and bubbles are blown out to the surroundings. Therefore, the user stops extracting the beer from the barrel as soon as a large amount of foam starts to appear, and uses another barrel. For this reason, there has been a problem that damage is caused by the ejection of foam or that beer in the barrel cannot be extracted to the end.

[0004] In order to solve the above problems, a foam blocker 149 is provided in the extraction pipe 146 as shown in FIG. That is, in the foam circuit breaker 149, as shown in FIG. 16A, for example, an operation is provided in which a float valve 184 is provided in a float chamber 183 in a case 182, and the float valve 184 is placed on the upper end of the case 182. A guide rod 187 suspended from the cap 186 is provided so as to be movable up and down about a central axis, floats on the beer introduced into the case 182, and according to a liquid level of the beer, a valve seat 189 is provided by a valve portion 185 at a lower end of the float valve 184. Is opened and closed. The beer extracted from the keg passes through the annular passage 202 from the introduction hole 201 of the nozzle forming body 200 embedded in the main body 197, and flows from the spout 204 at the tip of a plurality of nozzles 203 erected from the annular passage 202 to the float chamber. 18
3 to squirt. When liquid beer is spouted from the spout 204, the spouted liquid collides with the lower surface of the flange portion 205 provided on the float valve 184, and the force prevents the float valve from being drawn in by the flow of the foamed beverage. Also, by lifting the operation cap 186, the valve portion 185 is separated from the valve seat 189,
Beer is supplied from the outlet 206 to the cooler 148. In this device, the nozzle 20
Beer from the spout 204 of the 3
A guide 207 extending horizontally is provided at the tip of the ejection port so as to be guided to the flange 205 of No.4.

As shown in FIG. 17, a crank-shaped groove 188 is provided on the inner surface of the operation cap 186, and a projection 19 provided on the upper end of the case 182 is formed in the groove 188.
0 is engaged. Also, the void 1 in the float valve 184
A projection 192 is provided at the lower end of the guide rod 187 extending to 91.
When the operation cap 186 is raised together with the guide rod 187 as will be described later, the projection 192 comes into contact with the upper wall 193 of the float valve 184 to raise the float valve.

[0006] In the bubble breaker 149 using a float valve as described above, a float chamber 183 is provided from the nozzle 203.
When the draft beer entering the inside is sufficiently supplied in a liquid state, the draft beer is filled in the float chamber 183, and the float valve 184 is guided by the guide rod 187 to rise to the uppermost position. The valve part 185 is sufficiently separated from the valve seat 189, and the liquid beer is discharged from the outlet 20.
6 to the cooler. With almost no draft beer left in the barrel, the beer from the barrel contains a large amount of foam. Furthermore, when carbon dioxide gas that is applying pressure in the barrel also comes out, the float chamber 183 enters The draft beer for the liquid decreases, and the liquid level L as shown in FIG.
Gradually decreases. As a result, the float valve 184 descends, and finally, as shown in FIG. 16C, when the liquid level L further decreases, the valve portion 185 sits on the valve seat 189 and closes. This prevents high-pressure bubbles from escaping from the karan and prevents the bubbles from spreading around. In addition, a lock plate 199 that allows the guide rod 187 to be separated is provided on the operation cap 186 so as to protrude to the side.

When the foam circuit breaker 149 is periodically cleaned, the float valve 184 must be lifted and held in an empty state, so that the operating cap 186 is twisted to form a crank-type formed on the inner surface thereof. The groove 188 is moved while being guided by the projection 190, and is raised from the upper locking portion 197 of the groove 188 so that the projection 190 is located at the lower locking portion 198, and then rotated. Thereby,
As shown in FIGS. 17A and 17B, the guide rod 187 fixed to the operation cap 186 is raised, and the projection 192 at the lower end is engaged with the upper wall 193 of the float valve 184 being lowered. At the same time, the float valve 184 is raised, and this state is maintained to enable the cleaning operation. An air vent 210 is provided at the upper end of the case 182, and the valve portion is separated from the valve seat surface by pushing the knob 211 against a spring provided inside, so that gas inside passes through the outer periphery of the shaft of the knob 211. Through the opening 212 to the outside.

Conventionally, in the foamed beverage supply apparatus as shown in FIG. 15, when the gas pressure of carbon dioxide gas is supplied from the gas cylinder 144 into the barrel 140, the pressure is adjusted separately from the foam circuit breaker 149. Some are provided with a valve 152. That is, in the pressure adjusting valve 152, the temperature sensing cylinder 179 is fixed to the draft beer barrel 140, and the pressure of the sealed fluid in the temperature sensing cylinder 179 changes according to the temperature, so that the flow rate adjusting valve 152 such as a diaphragm valve is operated. Then, the pressure of the supplied carbon dioxide gas is increased as the temperature of the draft beer barrel 140 increases.

[0009]

In the above prior art, the inlet of the float chamber is formed by a nozzle, and the float valve is prevented from being drawn in by the flow of the sparkling beverage by the pressure of beer coming out of the nozzle, Since the beer is made to float, even if the foam in the beer flowing into the case increases and the liquid level in the case decreases, FIG.
As shown in Fig. 1, the float is prevented from descending by the flow of beer, and the float valve eventually closes the valve seat.
As shown in FIG. 6 (c), when the liquid level L is considerably lowered, depending on the increasing state of the internal bubbles, the responsiveness of the valve, etc., a part of the bubbles or the high-pressure carbon dioxide gas before closing the valve. There was a possibility that some would erupt.

Referring to the prior art shown in FIGS. 16 and 17 for the foam circuit breaker, when the float valve is released when the foam circuit breaker is mounted, washed, or barrel is replaced. In addition, the operation cap must be lifted and rotated, and at the time of barrel replacement, many steps including operations related to the barrel are required.

In addition, since the structure in which the nozzle is incorporated in the body is employed, there is a problem that beer accumulates in a gap between the body and the nozzle, which is not preferable for sanitation. further,
Since the structure is such that the float valve 184 and the guide rod 187 are connected, workability at the time of cleaning is poor, and the float valve 184 and the guide rod 187 have a structure that cannot be removed, and the inside of the float is difficult to clean. It is also unsanitary because it has become.

Further, in the prior art, a temperature and pressure adjusting device for supplying carbon dioxide gas having an appropriate pressure according to the temperature of draft beer into the barrel, and a bubble together with the high pressure carbon dioxide gas when the barrel is emptied. Since the foam circuit breaker for preventing the air from being blown out is formed separately, the cost is increased and the maintenance is troublesome. These problems are not limited to the supply of draft beer, but are also common problems in the supply of sparkling beverages.

Therefore, according to the present invention, when foam is supplied to the sparkling beverage supply path, the flow path can be shut off with good responsiveness, the operation of releasing the float valve can be easily performed, and the foaming can be performed in the flow path. It is an object of the present invention to provide a foamed beverage supply device having a configuration in which the beverage does not accumulate and having a foam circuit breaker that can easily clean the inside.

[0014]

[0017]

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a first embodiment of the present invention.
By attaching the temperature and pressure control device 4 to the side of the body 3 of the above, the foamed beverage supply device 1 in which these are integrated is constituted. The foam circuit breaker 2 has a float chamber container 55 fixed to the upper part of the body 3 by screwing.
An inner cylinder 56 protruding from the upper surface of the body 3 is arranged inside, and a gas-liquid separation plate 58 is inserted into the inner surface of the float chamber container 55 through a gap with the upper end 57 of the inner cylinder 56. . Float chamber 60 inside float chamber container 55
A fixing member 61 is inserted into the float chamber container 55 at the upper part of the container, and the fixing member 61 fixes four guide rods 62 as a guide mechanism. This guide rod 62
Penetrates the guide hole 65 of the flange portion 64 of the float valve 63, and thereby guides the float valve 63 so as to float on the liquid beer introduced therein and move up and down stably.

The gas-liquid separation plate 58 includes a top plate 66 which is a flat annular plate portion, a cylindrical fixing portion 67, and a tip end, as shown in a perspective view partially in section in FIG. Is formed of a tapered portion 68 whose diameter decreases toward the center and extends downward. The top plate 66 is provided with two holes 70 in the figure. The gap between the lower surface of the top plate 66 and the upper end portion 57 of the inner cylinder 56 becomes a liquid beer ejection opening 71, and the beer from the ejection opening 71 is guided by the tapered portion 68 and ejects downward. It has become.

The angle of inclination of the tapered portion 68 is preferably inclined at least 5 degrees downward from a horizontal line so that the beer to be ejected faces at least downward, and the jet flows toward the valve seat 84 located below the center. It is preferable to set the angle within 85 degrees. Experiments have confirmed that the opening area of the ejection opening 71 is preferably set at least within 15% of the inner diameter of the float chamber container 55 in order to form an appropriate jet.

On the other hand, the hole 70 is used for introducing bubbles or carbon dioxide in beer introduced into the gas-liquid separation plate 58 into the float chamber 60.
Works to pull in. For this reason, the tip 72 of the tapered portion 68 of the gas-liquid separation plate 58 is located below the upper end 57 of the inner cylinder 56 so that the beer stays inside and the gas can be easily separated. The hole 70 of the gas-liquid separation plate 58
If the opening area of is too large with respect to the opening area of the ejection opening 71 from which liquid beer is ejected, many liquid beers also flow into the float chamber from the hole 70, which is not preferable. If the size is too small, the beer bubbles will not sufficiently escape from the hole 70 and the gas-liquid separation will not be sufficiently performed. Therefore, the opening area of the hole of the gas-liquid separation plate will eventually be 20% of the opening area of the ejection opening. Experiments have shown that it is preferable to set it to 60%. The tapered portion 68 may be a curved portion formed in a curved shape other than the tapered portion having a straight cross section as in the illustrated embodiment.

The float valve 63 has a flange portion 64 formed at the upper end as described above. The flange portion 64 has a notch 69 formed by cutting a disk from the outer periphery at four places as shown in a perspective view in FIG. As a result, a guide rod 62 is loosely penetrated into the guide hole 65. The position of the notch 69 is arranged so as to be vertically aligned with the hole 70 formed in the top plate 66 of the gas-liquid separation plate 58,
The foam floating from the hole 70 does not hit the flange 64 to prevent the float from descending. The valve portion 73 extends downward from the center of the flange portion 64, and in order from the lower end of the valve portion 73, a hemispherical push-up portion 74, a float taper portion 75, a float cylindrical portion 76, and the float cylindrical portion 76
Horizontal step 78 from the upper end of the to the small body 77
Are respectively formed. An O-ring 80 is housed above the float taper 75.

At the lower end of the inner peripheral surface of the inner cylinder 56, a taper member 82 whose inner surface forms an inner cylinder taper portion 81 is inserted. A cylindrical portion 83 is formed. The lower end of the inner cylindrical portion 83 is tapered valve seat 84 formed on the body 3 of the foam circuit breaker 2.
When the float valve 63 is closed as shown in FIG. 1, the O-ring 80 abuts against the tapered valve seat 84 to perform a valve closing action. At this time, the float cylindrical portion 76 and the inner cylindrical portion 83 Are opposed to each other with a gap.

The outflow passage 85 of the body 3 is formed in a substantially L-shape, and a bent operation portion 87 is provided with a float operation rod 87 in FIG.
As shown in FIG. The float operating rod 87 is formed with a first notch 88 that is largely cut out in a planar shape, and a second notch 89 that is smallly cut at right angles to the first notch 88. During normal operation of the foam circuit breaker 2, the first notch 88 faces upward as shown in FIGS. 1 and 5 (a).
The push-up portion 74 at the lower end of the float valve 63 in the fully closed state has a gap and is set so as not to contact.

On the other hand, when it is necessary to forcibly open the float valve at the time of cleaning the float chamber or the like, the operation rod 87 is rotated from the outside, and the second notch 89 having a small notch amount is set so as to face downward. Then, FIG.
As shown in (b), the push-up portion 74 is lifted, and the float valve 63 as a whole rises, so that the O-ring 80 is separated from the valve seat 84 to open the valve, so that the float chamber can be cleaned or the like. As described above, the operation of opening the float valve is very simple, the number of steps involved in cleaning the inside of the foam circuit breaker can be reduced, and the cleaning operation can be easily performed.

The outflow passage 85 of the body 3 may be provided with a shut-off valve 90 for manually closing the flow passage as shown by a two-dot chain line in FIG. By shutting off the flow path with the shut-off valve 90 when the supply of beer is not required when not in use, the flow path is shut off at this part even if the shut-off valve in the carbon dioxide gas cylinder part is not closed. Inappropriate operation of the sparkling beverage supply device, such as excessive absorption of carbon dioxide in the subsequent portions, can be prevented.

Further, the above-mentioned float chamber entrance 92 is connected to
As shown in FIG. 5, the beer introduced into the gas-liquid separation plate 58 from the float chamber entrance 92 is disposed at a position separated from the hole 70 in the gas-liquid separation plate 58 covering the upper part thereof. The flow into the float chamber directly from the hole 70 is prevented as much as possible.

An air vent 94 as shown in FIG. 4 is provided at the upper end of the float chamber container 55. When the knob 95 is pressed against a spring 96, the valve portion 97 separates from the valve seat surface 98, and the gas inside the valve portion 97 is removed. Opening 9 through the outer periphery of the shaft of knob 95
9 to the outside. In addition, an O-ring 108 is provided on the knob 95 on the rear side of the opening 99 to prevent bubbles and gas from being applied to a person.

In the operation of the foam circuit breaker for the sparkling beverage supply apparatus constructed as described above, when the beer from the draft beer barrel enters the inflow path 14 from the entrance side opening 91 of the foam circuit breaker 2, it is provided to protrude. The collision with the temperature sensing portion 13 of the temperature sensing member 15 at a high speed, the temperature sensing member 15 directly detects the temperature of the beer. The beer that has entered the float chamber 60 of the foam circuit breaker 2 from the float chamber entrance 92 spreads upward into the hollow cylindrical flow path 29 formed around the inner cylinder 56 and flows upward, and the top plate of the gas-liquid separation plate 58 66. At this time, when the beer contains bubbles, it is discharged from the hole 70 formed in the top plate 66 to the upper part of the float chamber. At this time,
In the flange portion 64 of the float valve 63, the notch 69 exists just above the hole, so that bubbles rising from the hole portion 70 do not generate a force that prevents the float valve 63 from descending. Most of the liquid beer that has reached the gas-liquid separation plate 58 is jetted from a jet opening 71 formed between the lower surface of the gas-liquid separation plate 58 and the upper end portion 57 of the inner cylinder 56, and the jet direction is gas-liquid separation. It is guided by the tapered portion 68 of the plate and goes to the opening side of the lower valve seat. At this time, if the liquid beer is filled in the float chamber 60 in a predetermined amount or more, the float valve 63 is raised as shown in FIG. It is not affected by the flow.

When the beer flowing into the float chamber has a large amount of foam, the foam is separated by the gas-liquid separation plate 58 and floats from the hole 70 to the upper portion of the float chamber. When the amount increases, the float valve 63 floating on the liquid beer is guided by the guide rod 62 and drops as the liquid level decreases. Thereafter, when the float valve 63 descends to the position shown in FIG.
At this time, since the amount of foam in the beer has increased to a predetermined value or more, it is desired that the supply of beer be stopped immediately. Therefore, in the foam circuit breaker 2 of the present invention, the foam is ejected downward from the ejection opening 71. The flowing liquid beer hits the upper surface of the step portion 78 of the float valve 63, and the force forcibly lowers the float valve 63 regardless of the buoyancy of the float valve 63.

When the float valve 63 is lowered to the position shown in FIG. 8, the float cylindrical portion 76 below the float valve reaches a position facing the inner cylindrical tapered portion 81 of the tapered member 82. As a result, the flow of the beer spouting from the spout opening 71 is restricted, and the flow velocity increases, whereby the float valve 63 is sucked downward, and the float valve is drawn further downward. Further, the float valve 63 descends,
As shown in the enlarged view of FIG. 9 in particular, (b), when the float cylindrical portion 76 reaches a position facing the inner cylindrical portion 83 of the tapered member 82, the flow velocity around the float valve becomes extremely high, and Closes quickly and reliably. This closed state is shown in FIG.

FIG. 1 shows the results of a performance test in which the dimensions and the like of each member were variously set in the above foam breaker.
It is shown in FIG. FIG. 14 (a) is a graph showing how the bubble blocking characteristics change depending on the presence or absence of the notch in the float flange. When the notch as shown in the figure is provided,
The delay time between the supply of foam to the foam circuit breaker and the closing of the float valve is within the appropriate range over the entire range of the carbon dioxide gas pressure supplied to the barrel. It can be seen that there is substantially no response. FIG. 14 (b) shows the measurement of the bubble blocking characteristics by changing the size of the notch. The larger the notch, the shorter the delay time at the time of the bubble blocking, and conversely, the smaller the notch. In the notch D in the figure, it can be seen that when the pressure of the carbon dioxide gas into the barrel is 2.5 kgf / cm ² or more, the delay time increases rapidly, and the operation falls into a defective operation range. FIG. 14 (c) shows the positional relationship between the entrance of the float chamber and the hole formed in the gas-liquid separation plate.
The change in the delay time of the foam cut-off is measured.
When the position of the inlet of the float chamber and the position of one of the holes of the gas-liquid separation plate are superimposed as described above, the flow of the liquid in the float chamber becomes unbalanced, and the tendency of the delay time with respect to each pressure increases. It is lost and malfunctions occur at pressures above 3.5 kg f / cm ² . On the other hand, in the state in which both are separated from each other by 90 degrees as shown in B, it can be seen that good and stable characteristics are exhibited at all pressures. From this, the positional relationship between the entrance of the float chamber and the hole is expressed by a bubble. It turns out to be an important factor for the circuit breaker. FIG. 14 (d) shows the measurement of the characteristics of the float valve seat according to the size of the gap between the float cylindrical portion 76 and the inner cylindrical portion 83 of the tapered member 82 when the float valve is closed. It can be seen that when the gap is small, the bubble blocking properties are particularly excellent at low pressures. Conversely, when the gap is increased to 0.3 mm, the gaps fall into the defective operation range at low pressures. FIG. 14E summarizes, at a glance, the conditions under which the test for checking the margin of the bubble blocking characteristics shown in each of the figures was performed.
It is. In this figure, in addition to the test conditions, the conditions for setting the gap between the upper end of the inner cylinder and the gas-liquid separation plate and the conditions for setting the gap when the float valve descends are also shown. Also, in this figure, the presence or absence of the notch in the flange portion, the notch area, and the gap of the valve seat affect the foam blocking performance, and the position of the hole of the separation plate and the gap when the float valve descends are This indicates that the outflow performance is affected.

In the above-described embodiment of the foam circuit breaker 2, the valve portion of the float valve body is provided with the O-ring 80 provided on the float taper portion 75 and the float cylindrical portion 76 provided thereon. For example, as shown in FIG. 11, a hemispherical valve portion 125 may be provided at the lower end of the float valve 63, and the spherical portion may be brought into contact with the valve seat 84. Also at this time, the inner cylindrical portion 83 and the outer peripheral surface of the valve body 125 are opposed to each other with a gap. By using such a valve element,
There is no need to use an O-ring as in the above embodiment,
Various components of beer can be prevented from adhering to the O-ring portion, the number of parts can be reduced, and line contact is maintained in any state with respect to the valve seat, so that the valve closing action is surely performed. It can be carried out.

In the above embodiment, as an example of the means for lifting the float valve, the lever is operated to rotate the float operation rod, and the float cam is lifted by the operating cam portion. In addition, for example, FIG. As shown in the figure, the beer outflow passage 8 faces the lower end of the float valve 63.
The push-up rod 126 may be configured to be inserted into the inside from below. In this device, as shown in FIG. 12 (b), a knob 127 implanted in a rod 126 is fitted and guided in an inverted L-shaped groove 128 formed in the body 3, and when the float valve is lifted, the knob 127 is lifted. Is lifted along the groove 128 and rotated in the circumferential direction at the upper end thereof so that the knob 1
27 to hold the float valve open.
By using such an apparatus, it is possible to easily clean the foam circuit breaker as in the above embodiment.

[0034]

Since the present invention is constructed as described above, in the invention according to the first aspect, when bubbles are supplied, the flow path can be reliably shut off with good responsiveness, and the container to be extracted can be used. Can be prevented from being mixed with a large amount of bubbles, and damage due to ejection of bubbles containing high-pressure carbon dioxide gas from an extraction unit such as a cock.

According to the second aspect of the present invention, a step is provided on the outer periphery of the float valve, and when the float valve slightly descends, the jet flow is energized to quickly reach the lower valve section. When a sparkling beverage containing a large amount of foam is supplied into the float chamber, the supply can be immediately stopped by the float valve. Further, in the invention according to claim 3, since the opening area of the ejection opening is formed within 60% to 200% of the area of the outflow passage, the velocity of the jet can be sufficiently increased, and the supply to the float chamber can be performed. Can be reliably guided below the float chamber, thereby eliminating the lifting force of the float due to the jet flowing above the float chamber, without obstructing the closing operation of the float, When the float is lowered, the float can be forcibly operated in the closing direction by the force.

In the invention according to the fourth aspect, a gas-liquid separation plate is provided mainly for passing a gas layer at the hole and guiding the liquid layer at the plate portion, and the gas-liquid mixture is supplied to the gas-liquid separation plate. When it came, since the air layer was introduced from the hole into the upper part of the float chamber, it was possible to reliably prevent foam from being mixed into the foamed beverage supplied from the foam circuit breaker,
Katsuko's gas-liquid separation plate can guide the sparkling beverage so that almost only the foam flows above the float chamber, thereby preventing the float from rising due to the jet of the sparkling beverage. In the invention according to claim 5, the opening area of the hole of the gas-liquid separation plate is 20% to 20% of the opening area of the ejection opening.
Since it is formed within 60%, a decrease in the foam separation effect due to an excessively small opening area of the hole is prevented, and a large amount of the foamed beverage for liquids flows out of the hole due to the excessively large opening area of the hole. As a result, the amount of outflow from the jet opening is reduced, the outflow path is changed, and the amount of the outflow can be reduced to a range that prevents the float from promoting the operation of blocking the flow path.

In the invention according to claim 6, the gas-liquid separation plate is provided with a tapered portion or a curved portion whose tip is inclined downward, and the final tip of the tapered portion or the curved portion is 5 to 5 with respect to the horizontal line. Since it is set to be within the range of 85 degrees and is set to be lower than the height of the inner cylinder that forms the ejection opening together with the tapered portion or the curved portion, the foamed beverage ejected from the ejection opening is surely located in the lower central portion. The sparkling beverage can be guided to the valve seat side, and the foamed beverage stays in the gas-liquid separation plate, so that the gas-liquid separation can be reliably performed.
